Hi Eric,

Thanks for your email!

One of the (entirely justified!) criticisms you make is of the lack of
comments, and that's something we do work on when we have time. If you'd
like to identify specific places where more comments would be helpful,
we'll try to give those areas special attention. You could even supply
some yourself based on your own understanding of the code :-)

You use a separate bytecode analysis tool to read in Java 5 annotations
from compiled bytecode. Could this stage have been avoided if abc
supported Java 5, so that the annotations would presumably have been
available from the source?

You also mention that improving lexer extensibility to allow extra states
to be added would be useful. Can you give examples of how it would help

I also realised from reading your comments about modifying the ant build
file that this part isn't very extensible! Of course it's a fairly trivial
task, but perhaps it should be. I'm inclined to suggest that extensions
should be compiled into separate jar files to abc itself, but of course it
would then be a bit more of a nuisance to use them.

We'll add a new section for this kind of thing as soon as we get a chance
:-) Do you plan to make your extension available?
